It is well known that U bolts can detach a standard carabiner if it is hooked to one leg and pulled across the other. These eyes solve that problem but as said above you need two hands to clip on.
I have a U bolt low in the cockpit and always clip upwards so it would take a downward pull to unclip. I think most of my safety lines have Gibb style clips which should be better (the old cast ones rather than the later steel plate ones).
